Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a sealed container having a function of preventing liquid leakage of contents such as a domestic dish container.

[Conventional technology]

A conventional sealed container is composed of a container body and a lid provided with a packing for sealing on an inner peripheral portion, and further has a fastening fastener for the body, which is used as a fastener after the lid is put on the container body. It is a structure that is tightened and sealed. It is known that a fastener is provided with a hinge portion in such a sealed container and is integrally formed of a synthetic resin with a main body or a lid.

In a sealed container with such fasteners integrated, when the fasteners are tightened and sealed, the tightening force is directly applied to the hinges, and the hinges, which are relatively weak, are damaged and tightening becomes impossible. Or, the hinge part may be fatigued and the tightening may not be possible, resulting in liquid leakage.

[Problems to be solved by the invention]

The problem to be solved by the present invention is a container having a fastener integrally provided with a lid and provided with a hinge portion, or a container having a hinge portion which is structurally and materially fragile. An object of the present invention is to obtain a hermetically sealed container that can be sufficiently hermetically sealed without applying a force to a relatively thin hinge portion when hermetically sealed.

[Means and Actions for Solving Problems]

The hermetically sealed container of the present invention has a container body having a convex portion slightly protruding outward at an upper edge portion, a lid having an opening on a side surface, and a wedge portion, and is rotatably attached to the lid. It is configured with a fastener, and when the opening formed in the lid is closed on the container body, the lower side of the convex portion formed on the upper edge of the container body and the lower side portion of the opening formed on the side surface of the lid The wedge part provided in the fastener is press-fitted between the two.

Since the sealed container of the present invention is constructed as described above, the lid of the container body is capped, and the wedge portion of the fastener is inserted through the opening formed in the side surface of the lid so that the upper end edge of the container body is convex. A wedge portion is press-fitted between the portion and the lower side portion of the opening so that the wedge acts on the container body and the lid in a direction toward each other to seal the container.

〔Example〕

Next, an embodiment of the sealed container of the present invention will be shown based on the drawings. 1 to 3 are views showing a first embodiment of the present invention, in which 1 is a container main body having a convex portion slightly protruding outward at an upper edge portion 7, 2 is a lid, Reference numeral 3 is a fastener that is rotatably integrally attached to the lid 2 by providing a hinge portion 3a such as a self-hinge. This fastener 3
Is composed of a plate-shaped body 4 and a wedge portion 5 projecting from the plate-shaped body 4. Further, the lid 2 is formed with an opening (hole 6) to be inserted when the fastener 3 is rotated.

In such a hermetically sealed container, the container body 1 is covered with the lid 2 to bring it into the state shown in FIG. 2, and the fastener 3 is rotated in the direction of the arrow so that the wedge portion 5 of the fastener 3 is inserted into the hole 6. When inserted and pushed in, the state shown in FIG. 3 is obtained. In the state shown in FIG. 3, one surface (lower surface in FIG. 3) of the wedge portion 5 of the fastener 3 pushes the lower side of the hole 6 of the lid 2 and the other surface of the wedge portion 5 (first surface). The tip end of the upper surface (in FIG. 3) is sealed by pushing upward the protrusion formed on the upper edge 7 of the main body 1.
That is, as shown in FIG. 2, if the wall thickness t ₁ of the wedge portion 5 is equal to or slightly larger than the interval t ₂ , it is press-fitted by utilizing the elasticity of the synthetic resin, and after the press-fitting, the container is formed by the action of the wedge. Sealed.

It should be noted that it is convenient to remove the fastener 3 if the tip 8 of the plate-like body 4 is slightly above the lid 2 as shown in FIG. 3 when the fastener 3 is closed.

In this embodiment, since the sealing action is performed only by the wedge portion 5, no force is applied to the fragile hinge portion 3a.

FIG. 4, FIG. 5, and FIG. 6 show another second embodiment.
In this embodiment, the hinge portion 3a is provided above the edge portion of the lid 2. By lowering the fastener 3 from the state shown in FIG. 5, the wedge portion 5 provided on the plate member 4 of the fastener is opened. 6 and is sealed as shown in FIG. 6 as in the first embodiment. Also, when opening the lid, the tip 8 of the fastener located below
Should be raised.

FIG. 7 is a diagram showing a third embodiment of the present invention. In this embodiment, instead of a plurality of holes for inserting the wedge portions, notches 9 are partially formed on the lower side of the flange portion of the lid, and projecting portions 10 on which the wedge portions are hooked are formed at both ends thereof. As a result, as in the second embodiment, when the fastener is rotated in the direction of the arrow and the wedge portion provided therein comes to the position of the notch 9, the protrusion 10 and the upper end of the container body are pushed to seal the container. To do.

The opening into which the wedge portion is inserted as in the third embodiment does not have to be the hole as in the other embodiments, but has the protrusion 10 or the like with which the lower surface of the wedge portion hangs. Any material can be used as long as it can be brought into close contact with the lid. Therefore, in the present invention, the one having the same effect as the holes of the other embodiments is obtained, including the shape of the notch 9 of the third embodiment and the projection 10 formed in this portion. Call it simply an opening.

FIGS. 8, 9, and 10 are views showing a fourth embodiment of the present invention. Example 4 is an example in which the wedge portion of the fastener is different. That is, the wedge portion 11 provided on the plate-like body 4 of the fastener 3
Is composed of two wedge pieces 11a and 11b.

In this embodiment as well, as in the other embodiments, the fastener 3 is rotated from the state shown in FIG. 9 to seal the lid as shown in FIG. One wedge piece 11 inserted into the hole 6 here
In a, the container body is pushed and another wedge piece 11b pushes the lid to seal it.

In this embodiment, since the wedge portion is divided into two, each wedge piece becomes slightly thin, which increases elasticity. Therefore, pushing of the wedge piece becomes easier and tightening becomes stronger.

FIG. 11 is a view showing another example of the container body of the hermetically sealed container of the present invention. The main body of the container has a protrusion on the side wall and outer surface.
12 is provided. In the case of this body, a wedge portion for sealing comes under the projecting portion 12 to seal the lid to the container body.

It should be noted that any of the examples can be integrally molded with synthetic resin. In addition, molding can be performed without using a complicated mold such as a split mold.

[Effect of device]

Since the present invention has the structure as described above, the lid is sealed by inserting wedges into both sides of the container body and the lid to apply forces in opposite directions (direction in which the lid comes into close contact with the body). Since the hinge is simply sealed and rotatably attached to the lid, no force is applied to the hinge, and the hinge is hardly damaged.
